20mm Hoisting Chain: Here, '20mm' usually refers to the nominal diameter of the chain, which is the size used for manufacturing and marking the specifications of the chain. It is one of the key parameters of the chain that directly determines its strength and lifting capacity. Core Characteristics and Applications: The 20mm hoisting chain belongs to high-strength lifting tools and is commonly used in the heavy industrial sector. · High breaking strength: Capable of withstanding large tensile forces. · Outstanding durability: Wear-resistant, impact-resistant, suitable for harsh industrial environments. · High temperature adaptability: Compared to steel wire ropes, it is more suitable for use in certain temperature conditions (but attention must be paid to the material grade). · Main applications: Port terminals, large equipment manufacturing and installation, power station construction, shipyards, heavy machinery hoisting, etc., where loads ranging from several tens to hundreds of tons need to be lifted.
